Download or read book The Devil s Cormorant written by Richard J. King and published by University of New Hampshire Press. This book was released on 2013-09-22 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behold the cormorant: silent, still, cruciform, and brooding; flashing, soaring, quick as a snake. Evolution has crafted the only creature on Earth that can migrate the length of a continent, dive and hunt deep underwater, perch comfortably on a branch or a wire, walk on land, climb up cliff faces, feed on thousands of different species, and live beside both fresh and salt water in a vast global range of temperatures and altitudes, often in close proximity to man. Long a symbol of gluttony, greed, bad luck, and evil, the cormorant has led a troubled existence in human history, myth, and literature. The birds have been prized as a source of mineral wealth in Peru, hunted to extinction in the Arctic, trained by the Japanese to catch fish, demonized by Milton in Paradise Lost, and reviled, despised, and exterminated by sport and commercial fishermen from Israel to Indianapolis, Toronto to Tierra del Fuego. In The DevilÕs Cormorant, Richard King takes us back in time and around the world to show us the history, nature, ecology, and economy of the worldÕs most misunderstood waterfowl.

Download or read book Interactions Between Fish and Birds written by Ian G. Cowx and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.

Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
Download or read book Intertidal Ecology written by D. Raffaelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seashore has long been the subject of fascination and study - the Ancient Greek scholar Aristotle made observations and wrote about Mediterranean sea urchins. The considerable knowledge of what to eat and where it could be found has been passed down since prehistoric times by oral tradition in many societies - in Britain it is still unwise to eat shellfish in months without an 'r' in them. Over the last three hundred years or so we have seen the formalization of science and this of course has touched intertidal ecology. Linnaeus classified specimens collected from the seashore and many common species (Patella vulgata L. , Mytilus edulis L. , Littorina littorea (L. )) bear his imprint because he formally described, named and catalogued them. Early natural historians described zonation patterns in the first part of the 19th century (Audouin and Milne-Edwards, 1832), and the Victorians became avid admirers and collectors of shore animals and plants with the advent of the new fashion of seaside holidays (Gosse, 1856; Kingsley, 1856). As science became professionalized towards the end of the century, marine biologists took advantage of low tides to gain easy access to marine life for taxonomic work and classical studies of functional morphology. The first serious studies of the ecology of the shore were made at this time (e. g.

Download or read book Early Life History and Recruitment in Fish Populations written by R.C. Chambers and published by Springer Science & Business Media. This book was released on 1997-07-31 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.
